What is motorcycle throttle body?

In fuel injection engines, the throttle body is part of the intake system, which controls the amount of air flowing into the engine and responds primarily to the input of the driver's accelerator pedal. Motorcycle throttle body is located between the intake filter and intake manifold butterfly valve. It adjusts the amount of air that can enter the engine based on the driver's input through the accelerator pedal. As more air flows into the engine, it ejects more fuel, providing more power.

What is the role of motorcycle throttle body?

1.      In the intake system, there is a housing unit containing the throttle plate, which is one of the components of the throttle body. Also known as a butterfly valve, the plate rotates on a shaft.

2.      When the driver presses the accelerator pedal, the throttle plate opens to allow air into the engine. Valve closes when pedal is released. This stops or throttles the airflow in the combustion chamber, which helps control the engine's speed.

3.      Throttle bodies can be found in different areas depending on the engine type of the vehicle. Older models often have throttle bodies built directly into the carburetor for fuel injection.

4.      The throttle body of a new fuel injection engine is usually located between the intake manifold and the air filter. The throttle body is mechanically connected to the accelerator pedal by wire or cable.

How to maintain motorcycle throttle body?

1.      Dirt, carbon, and dirt can build up in the enclosure, causing airflow problems. Called coking, the normally smooth air travel service becomes sticky and unbalanced. This interrupts the perfect mixing of air and fuel, which can cause the butterfly valve to jam.

2.      While throttle body cleaning is good for preventative car maintenance, it should also contribute to engine drivability. In fact, if you notice an unsteady idle, wobbly initial acceleration or even stalling -- all of which happen when the engine is fully warmed up -- a dirty throttle body could be the culprit.

3.      Ideally, you should perform routine fuel injection system maintenance and throttle body cleaning every 75,000 miles. This also includes checking oxygen sensors and catalytic converters for any signs of damage.
